How to return to lightrooms classic view

[defaultfpu944rkipzz]

Hello,

Only recently I started using lightroom classic and thus I am pretty inexperienced and I am sure this is merely a matter of me not having a clue how this happened or what I do next. However I would really appreciate the help.

I was going through my last set of photos making selections while all of a sudden the classic way lightroom has always looked split into two windows - like you can see in the screenshots. The full view of the image was before I force closed lightroom completely fullview and I was not able to minimize it or interract with it. Upon opening lightroom again this is how it looks.

Normally the fullscreen view of the image can just be closed with Esc and then you'd return to the normal library view. Right now I have no clue how to get back to seeing my collections or library as a whole.

If anyone could help a newbie I would be forever grateful

Pressing Tab will hide/show the side panels.

Pressing F5 will hide/show the Module picker.

Pressing F6 will hide/show the Filmstrip.

Pressing F7 will hide/show the left panels.

Pressing F8 will hide/show the right panels. 

You can also click the little grey arrows at the edges of the screen to show/hide the panels manually.

Right click the arrows for more options.

In the future, please do not attach screenshots, use the Insert Photos button in the toolbar to embed them in your posts.

I open my library and within seconds a white square opens over library with word CLOSE appears, blocking my access.

As this obviously has nothing to do with the topic, please open a new thread for your question .... and there, add much more details, ideally including a screen capture.
